TECHNICAL FIELD OF THE INVENTION

The present invention relates to a mechanism developed to be used in firearms for ensuring the easy removal and installation of a removable firearm barrel for the purposes of both making the barrel bore ready for firing prior to shooting and for cleaning the firearm barrel after firing when necessary. The present invention particularly relates to a mechanism connected to the body of the firearm, which allows the rapid removal of the firearm barrel without requiring an additional wedge key.

PRIOR ART

Ammunition fired through firearm barrels leaves a substantial amount of residue due to the impact of the explosion as a consequence of the firing action realized in a rather confined space after pulling the trigger in firearms. Cleaning this residue is crucial for the smooth functioning of the mechanism.

Gun cleaning is of pivotal importance not only after but also before firing. This cleaning process not only prevents the firearm from potential misfires, but also prolongs the physical life of the gun and reduces metal fatigue. Firearm barrels are manufactured to have both removal and reinstallation characteristics so as to ensure that this cleaning procedure may be performed.

A certain part of firearm barrels having the capability of removal-installation characteristics may feature passes. Barrel installation is performed by means of connecting the pass that extends at the portion in which firearm body is engaged with the firearm barrel, with another pass that extends at the portion where the firearm barrel is engaged with the firearm body. Whereas the removal is performed by unscrewing the firearm barrel when said barrel is desired to be removed for the purpose of cleaning. However, aforementioned passes, being extended at both firearm body and firearm barrel, pose a number of problems. Thinning of wall thickness of the firearm barrel is the foremost among these problems. Concordantly, thinning in the wall thickness of the firearm barrel results in a reduction in the body strength thereof. On the other hand, the operator may potentially face life-threatening hazards if the weapon is fired in cases where aforementioned passes cannot be engaged properly.

Another barrel type having removal-installation characteristics is the barrel that is connected to the body by means of a screw formed at the area where the barrel cap is connected to the barrel. However, differently from aforementioned barrel technique which comprises of passes, this removal-installation process requires an additional screw key. Said screw key allows the user to screw the barrel to the firearm body or unscrew it therefrom. However, if this key gets lost it becomes impossible to remove or to reinstall the firearm barrel which consequently imposes an additional burden on the operator.

OBJECTS OF THE INVENTION

The present invention relates to a rapid removal-installation mechanism for firearm barrels which eliminates drawbacks existing in the prior art.

The mechanism which is formed at the lower portion of said firearm body for the purpose of securing the barrel thereto, presses down on a ring which is called claw pressing surface situated on the barrel. The mechanism is released, and the pressure applied to said claw pressing surface is dissipated when the barrel is going to be removed. Thus, the barrel may easily be removed from the firearm body for purposes such as cleaning and/or any other procedure. When the barrel is desired to be reinstalled to the firearm body, it gets seated into the body and the mechanism is drawn unto the barrel. Hence, the mechanism gets locked, thereby securing said barrel to the firearm body.

The inventive mechanism which does not require any additional part such as a spanner or a key, does not impose any weaknesses or cause exhaustion on the firearm body as well as on the barrel.

On the contrary, the inventive mechanism ensures that the barrel gets fixed to the firearm body in a more secure manner.

By means of the inventive rapid removal-installation mechanism for firearm barrels;

-   -   The barrel may be removed for cleaning and/or any other         procedures in a span of time briefer than 10 seconds,     -   The barrel may once again be reinstalled to the body of the         firearm in a span of time briefer than 10 seconds,     -   It is ensured that the barrel is installed to the body at a         correct angle,     -   Safety problems which exist in the prior art and arise while the         barrel is being installed to the body are eliminated,     -   And the physical life of the barrel is extended.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a rapid removal-installation mechanism for firearm barrels, wherein one of the main components thereof is the removal-installation lever (9) as illustrated in FIG. 6. The body of the removal-installation lever (9) is composed of two walls which are parallel to one another. A latch spring seat (16) is positioned in an expanded manner between said walls. A latch pin seat (17) is located at the lower portion of the latch spring seat (16). Forked end (21) which is located under the latch pin seat (17) has a U shape and pressing claws (14) are positioned on both of aforementioned forked ends (21). Both of said pressing claws (14) are positioned on forked ends (21) in an angulated (e.g. at 90°) manner.

As illustrated in FIG. 8, locking latch (11) has a latch pin hole (12) created thereon, and comprises a latch tab (13) formed with a certain curvature by taking said latch pin hole (12) as a center. Pressing end (23) is located at the other end of the locking latch (11).

Aforementioned locking latch (11) is positioned on the latch spring (10) after said latch spring (10) is connected to the latch spring seat (16). Latch pin hole (12) which is created on the locking latch (11), and latch pin seat (17) which is created on the removal-installation lever (9), are aligned and secured by means of a plurality of pins (6) inserted there between. Latch spring (10) pushes the locking latch (11) out of the removal-installation lever (9) from the pressing end (23). Latch tab (13) which is located at the other end of the locking latch (11) moves when the force is applied on to the latch spring (10) over the pressing end (23).

As illustrated in FIG. 5, another main component of the present invention is the body connection wall (22), wherein said wall is comprised of two parallel walls connected at the position in which they are fixed to the lower portion of the body (1). Said walls comprise one lever pin seat (8), and two adjusting gear pin seats (18) which are created so as to allow the engagement of the adjusting gear (5).

Adjusting gear (5) has a rectangular structure and comprises two adjusting gear pin holes (20) created thereon. An outer wall of said adjusting gear (5) has a curved form, and threads (19) which are parallel to each other, are situated on said curved surface.

Adjusting gear (5) is positioned between the body connection wall (22). Subsequently, the adjusting gear pin seat (18) is aligned with the adjusting gear pin holes (20) which are created on said adjusting gear (5), and accordingly, a plurality of pins (6) is inserted through said holes. Thus, adjusting gear (5) is fixed to the body connection wall (22).

As illustrated in FIG. 4, yet another main component of the present invention is the claw pressing surface (3). Said claw pressing surface (3) encircles the barrel (2) at the position in which the barrel cap (4) and the barrel (2) are connected.

Lever pin hole (15) is positioned between the body connection wall (22) so as to connect the removal-installation lever (9) which is one of the main components of the present invention, to the body (1). Subsequently, the lever pin hole (15) and the lever pin seat (8) are aligned, and at least one of the plurality of pins (6) is inserted therethrough.

Barrel cap (4) is seated inside of the cap seat (7) which is located on said body (1), when the barrel (2) is desired to be reinstalled to the body (1). Claw pressing surface (3) creates the margins which designate the barrel cap's (4) insertion limits to the cap seat (7).

Subsequently, removal-installation lever (9) is started to be pulled towards the barrel (2) that comes to rest in a parallel manner. When the removal-installation lever (9) is brought in close proximity of the barrel (2), the latch tab (13), being one of the ends of the locking latch (11) traverses over the first thread (19) located on the adjusting gear (5). Each time the latch tab (13) traverses over each thread (19) it gets locked by means of the pressure of the latch spring (10). The latch tab (13) traverses the last thread (19) once the pressing claw (14) becomes fully seated on the claw pressing surface (3). Since the threads (19) are located on the curved surface of the adjusting gear (5), and as the latch spring (10) provides room for flexibility to the locking latch (11) by taking the latch pin hole (12) as a center, every time the removal-installation lever (9) traverses each one of the threads (19), it begins to retain the claw pressing surface (3).

In case the barrel (2) is desired to be removed from the body (1), said latch spring (10) stretches when pressure is applied to the locking latch (11) towards the latch spring (10) over the pressing end (23) and accordingly, the latch tab (13) moves from the last thread (19) in which it gets seated. Thus, removal-installation lever (9) is moved away from the barrel (2), and the pressing claw (14) releases the barrel (2) by lifting off of the claw pressing surface (3). Subsequently, the barrel (2) is removed from the body (1) by being pulled therefrom.

Removal-installation lever (9) which is one of the main components of the present invention may also be comprised of a single wall as illustrated in FIG. 11. Aforementioned removal-installation lever (9) comprises the latch pin seat (17) situated thereon. Lever pin hole (15) and pressing claw (14) are positioned on the end portion which remains under the latch pin seat (17).

In case the removal-installation lever (9) is arranged in the manner illustrated in FIG. 11, the locking latch (11) may also have the structure illustrated in FIG. 13. In that case, aforementioned locking latch (11) is provided a latch pin hole (12) created at one of ends thereof and comprises a latch tab (13) which is created to have a curved form by taking aforementioned latch pin hole (12) as a center. Spring base (24) is located at the other end of said locking latch (11). The latch spring (10) is positioned between the removal-installation lever (9) and said spring base (24).

The locking latch (11) is positioned on said latch spring (10) after the latch spring (10) is connected to aforementioned removal-installation lever (9). Subsequently, latch pin hole (12) created on the locking latch (11) and latch pin seat (17) created on the removal-installation lever (9) are aligned, and accordingly secured by means of at least one of the plurality of pins (6) inserted therethrough. Aforementioned latch spring (10) pushes the locking latch (11) towards the outside of the removal-installation lever (9) through the spring base (24). The latch tab (13) which is located at the other end of the locking latch (11), moves when force is applied on to the latch spring (10) over the spring base (24).
